@danmoyle We already use sandbox for testing and I thoroughly checked the article. It is helpful but I was looking more on how to simulate the test cases (avoid to test manually) and ensure that future changes will maintain the whole business logic. Because when you have multiple workflows for a process it is important to make sure that any change you implement in one of them does not affect the others and the final result. So by having automated tests you know that everything works as it should after your changes (you didn’t break anything). And based on that I wanted to check whether other teams implement any kind of integration tests approach for hubspot and whether there are best practices ( For example create tickets with hubspot api , changing status and then (after workflows triggered ) assert the outcomes with a testing framework like Jest ). Anyway, thanks so much for your answers. We appreciate it!
